The MAX1428 is a 5V, high-speed, high-performance analog-to-digital converter (ADC) featuring a fully differential wideband track-and-hold (T/H) and a 15-bit converter core. The MAX1428 is optimized for multichannel, multimode receivers, which require the ADC to meet very stringent dynamic performance requirements. With a noise floor of -78.4d BFS, the MAX1428 allows for the design of receivers with superior sensitivity. The MAX1428 achieves two-tone, spurious-free dynamic range (SFDR) of -82d Bc for input tones of 69MHz and 71MHz. Its excellent signal-to-noise ratio (SNR) of 73.9d B and single-tone SFDR performance (SFDR1/SFDR2) of 83d Bc/91d Bc at f IN = 70MHz and a sampling rate of 80Msps make this part ideal for high-performance digital receivers. The MAX1428 operates from an analog 5V and a digital 3V supply, features a 2.56VP-P full-scale input range, and allows for a sampling speed of up to 80Msps. The input T/H operates with a -1d B full-power bandwidth of 260MHz. The MAX1428 features parallel, CMOS-patible outputs in two’s-plement format. To enable the interface with a wide range of logic devices, this ADC provides a separate output driver power-supply range of 2.3V to 3.5V. The MAX1428 is manufactured in an 8mm x 8mm, 56-pin thin QFN package with exposed paddle (EP) for low thermal resistance, and is specified for the extended industrial (-40°C to +85°C) temperature range. Note that IF parts MAX1418, MAX1428, and MAX1430...
